2. Saugos informacija

To ensure safe operation and prevent damage to the meter, please read and follow all safety instructions carefully. Improper use can result in electric shock or damage to the instrument.

• Always verify the meter's functionality before use by testing a known voltage arba srovės šaltinis.
• Neviršykite kiekvienam matavimo diapazonui nurodytų didžiausių įvesties verčių.
• Ensure test leads are in good condition, free from cracks or damaged insulation, before connecting them to any circuit.
• Never use the meter if it appears damaged or if the casing yra atidarytas.
• Būkite ypač atsargūs dirbdami su ttagesant didesnei nei 30 V AC RMS, 42 V pikinei vertei arba 60 V DC įtampai. Šie įtampų lygiaitagtai kelia šoko pavojų.
• Remove test leads from the circuit before changing functions or ranges.
• Kad užtikrintumėte tikslius rodmenis, nedelsdami pakeiskite baterijas, kai pasirodys išsikrovusių baterijų indikatorius.
• Nenaudokite matuoklio sprogiose dujų, garų ar dulkėtose aplinkose.

6. Naudojimo instrukcijos

6.1 Maitinimo įjungimas/išjungimas

Paspauskite raudoną maitinimo mygtuką (Įjungimo mygtukas) to turn the multimeter on or off. The device features an auto-shutdown function to conserve battery life after a period of inactivity.

6.2 Matavimo režimai

The multimeter offers two primary measurement modes:

Figure 5: The multimeter supports both auto identification and manual switching modes.

• Auto Identification Mode: When powered on, the meter defaults to auto identification. In this mode, it automatically detects and measures AC/DC voltage, frequency, resistance, and continuity. Simply connect the test leads to the circuit, and the meter will display the relevant measurement.
• Rankinis perjungimo režimas: To access specific functions not covered by auto identification or to manually select a range, press the 'NCV/LIVE' button (or other function buttons if available on your specific model, e.g., FY129C for Diode/Capacitance). This allows you to cycle through AC/DC voltage, frequency, resistance, continuity, LIVE, and NCV.

6.3 AC/DC matavimas Voltage

1. Connect the black test lead to the 'COM' jack and the red test lead to the 'INPUT' jack.
2. If in auto identification mode, the meter will automatically detect voltage. If in manual mode, select the appropriate AC or DC voltage funkcija.
3. Prijunkite bandymo laidus lygiagrečiai prie matuojamo komponento arba grandinės.
4. Perskaitykite ttage reikšmė LCD ekrane.

6.4 Atsparumo matavimas

1. Prieš matuodami varžą, įsitikinkite, kad grandinė yra atjungta nuo įtampos.
2. Connect the black test lead to 'COM' and the red test lead to 'INPUT'.
3. If in auto identification mode, the meter will automatically detect resistance. If in manual mode, select the resistance function (Ω).
